The answer is C (1, 3) since it’s the only point on the graph that’s on the line perfectly on both the x axis and the y axis.

6 4/5 + 7 4/5 = what
swat32
Multiply 6x5= 30, 30 + 4 = 34
Then 7x5= 35, 35 + 4 = 39
34+39 = 73
73/5 = 14.6 or 14 3/5

What is the solution for<br> x + 10 = -5
scZoUnD [109]

Answer: X=-15

Step-by-step explanation:

x+10=-5

Move constant to the right side and change its sign

X=-5-10

You would then dilate the differences!

What is the extraneous solution found in solving the equation log2 4x + log₂ (x + 1) = 3
yan [13]

Answer:

x = -2

Step-by-step explanation:

We are given the logarithmic base 2 equation of:

\displaystyle{\log_2 (4x) + \log_2 (x+1) = 3}

Apply logarithm property of addition where:

\displaystyle{\log_a M + \log_a N = \log_a MN}

Therefore, we will write new equation as:

\displaystyle{\log_2 [4x(x+1)] = 3}

Apply logarithm to exponential form using:

\displaystyle{\log_a M = N \to a^N = M}

Thus, another new rewritten equation is:

\displaystyle{2^3 = 4x(x+1)}\\\\\displaystyle{8 = 4x(x+1)}\\\\\displaystyle{2=x(x+1)}

Expand the expression in and arrange the terms in quadratic expression:

\displaystyle{2=x^2+x}\\\\\displaystyle{0=x^2+x-2}\\\\\displaystyle{x^2+x-2=0}

Solve for x:

\displaystyle{(x+2)(x-1)=0}\\\\\displaystyle{x=-2,1}

These are potential solutions to the equation. To find extraneous solution, you’ll have to know the domain of logarithm function. We know that logarithm’s domain is defined to be greater than 0. Henceforth, anti-logarithm must be greater than 0.

( 1 ) 4x > 0, x > 0

( 2 ) x + 1 > 0, x > -1

Therefore, our anti-log must be greater than 0, so any solutions that are equal or less than 0 will be considered as extraneous solution.

Hence, x = -2 is the extraneous solution.
